Preserve dots in parameters in RequestQueryHelper. Fixes #236

[neildaniels]

• Fixes RequestQueryHelper unexpectedly converts dots/periods in parameters to underscores #236

parse_str converts periods/dots in parameters to underscores, which ruins TMDb keys such as air_date_gte

This is a naive implementation of query string parsing, but hopefully is adequate in this context.

Sorry for the late pickup; just noticed the ticket ( I am not on github much within my current work environment ), good catch of a never catched "edge-case" :-). I'm not sure if I agree with the way the problem is being solved though, gonna set up to play with this in a bit.

@neildaniels given I didn't feel like I would have agreed with this solution to fix #236, I created a unit test to verify the issue exists to begin with, however either the problem lies elsewhere, or I just don't understand how to reproduce this issue.

Could you rebase on the latest 4.0 branch and modify the change introduced with ef9a246 to validate the case actually fails?

@neildaniels disregard my last message; whilst tinkering more and more I was able to reproduce

[neildaniels]

@wtfzdotnet Can this get merged in?

[wtfzdotnet]

Sorry @neildaniels , I'll take a look after work in like 5 hours.

@neildaniels I'll get back to this at another time (and see if I can find a fix that feels better to me), github isn't really on my radar so do tag me like that if it takes a while :-)... Distracted with other projects and work, busy life!
